I'm one of the developer of this game and i thank you for playing, rating and give your opinion about the game. We will take note of what you said and try to improve the game with your comment.
The hitbox of barrels are too small and it can be frustrating i admit, so i think we will make an upgrade on this.
At the end if you move upward you should find your dad, but there is a bug that delete dad from the save when you die once so he might not appear.
We made really simple menu because of out short amount of time (even if we were four, we were a team with only beginner and it was our first experience) and even the sound made by one of our team mate was not added just because of the time left (which we find really deceiving that his work don't appear even if he worked pretty hard)
The save and load work but only if you don't die, when you die your save will make you restart from the beginning with the footsteps from before.
Thank you again for your feedback and I hoped you enjoyed the experience
